#CulturalAppropriation CONFUSION! Where Are the Lines Drawn?

For the past two years, there has been a very HEAVY discussion of cultural appropriation on social media. For those of you who are unaware, cultural appropriation is defined as: " is the adoption or use of elements of one culture by a member or members of a different culture. Cultural appropriation may eventually lead to the imitating group being seen as the new face of said cultural practices." (According to Wikipedia)There has been public scrutiny and backlash of celebrities like Miley Cyrus, Iggy Azalea, Katy Perry, Lily Allen, Justin Timberlake, and many more accused of participating in cultural theft. Here are a few photo examples:

Those are pretty clear examples of cultural appropriation that some White people in the music industry and pop culture have been partaking it. It alludes to the notion that people of color are degraded for celebrating their culture, but when a White person does it, these pieces of clothing, physical features, vernacular, etc are praised. Many media outlets have also attempted to credit White celebrities as the founders of certain hairstyles like bantu knots.

With this being said, my confusion about cultural appropriation came to be when seeing people of color "appropriating" cultures from other peoples of color. Here are a few examples:

Japanese hip hop culture is very affluent in cities like Tokyo. Hip hop culture was founded in urban Black America. Is this man wearing an afro and "urban hip hop wear" appropriation?

In laments terms, where are the lines of cultural appropriation drawn at? Is it only an issue when White people participate in it? Is it an issue when African Americans adorn themselves in African clothing although they did not grow up in places like Nigeria or Cameroon? Are tattoos in languages such as Arabic appropriation? What are your thoughts about the extended conversation about cultural appropriation?
